Product questions
What current range and trip class does ABB 1SAZ421201R1006 have?
The TA200DU-200 has an adjustable current setting range of 150–200 A and a class 10A trip characteristic. Check the motor nameplate and protection requirements before selecting the relay.
What protection does the TA200DU-200 provide?
This three-pole thermal overload relay provides motor overload and phase-failure protection. Short-circuit protection must be selected separately; the relay is not a substitute for a properly rated short-circuit protective device.
Does the TA200DU-200 offer manual and automatic reset?
Yes. The relay has selectable manual or automatic reset, a trip indicator, and TEST and STOP functions. It also has temperature compensation.
How can I check whether this relay will fit my contactor?
The relay connects directly to compatible block contactors; a separate mounting kit is available. Verify the exact contactor model, equipment details and, where applicable, serial number before ordering; compatibility cannot be established from the relay number alone.
What auxiliary contacts are included on the TA200DU-200?
The relay has one normally closed trip contact and one normally open signalling contact. Check the control circuit voltage and contact ratings for the intended application.
